Anilinium chloride is the organic compound with the formula C₆H₅NH+3Cl⁻. A white solid, it is the chloride salt of anilinium, which is the conjugate acid of aniline, C₆H₅NH₂. Anilinium chloride is produced by treatment of aniline with hydrochloric acid. The cation consists of a phenyl ring attached to a tetrahedral ammonium center. The C-N bond elongates from 1.41 Å in aniline to 1.474 Å in anilinium.^[2]
